Getting a JSON error when trying to update anything on the home page.

[gencho1980]

Hello,

We're getting a "Updating failed. Error message: The response is not a valid JSON response." every time immediately after I try to update and save any content on the home page. The content does not get updated, but this error does not happen on other pages, only on the home page.

The site is WordPress 5.3.2 running Sydney Child theme with few other plugins. The site was error free originally, not sure what could cause this to happen over time.

Not sure if its possible, but I'm going to try and attach the screenshot of that error.

Please let me know if you need further info to help troubleshoot.

Your help is much appreciated!

Thanks

Genrik

Hi @gencho1980,
Welcome to WordPress Trac, reporting tool. A debt of gratitude is in order for the report.

I wish to know, Is there any block to REST API?

Thank you

Thank you for the quick response. Honestly I'm not sure (its been a while), but I just did a full page screenshot of all the plugins that are installed and will attach to this ticket. I don't want to go forward with updating any of them yet not to break anything else. Does this screenshot help? Please let me know if I need to dig somewhere else.

Thanks!
